Solve the following equation for the variable x?
Favorite Answer
6(x+1) / (x-1) (x+1) + 5(x-1) / (x+1) (x-1) = 3x/x^2-1
6(x+1) / x^2 – 1 + 5(x-1) / x^2 – 1 = 3x/x^2 – 1
6(x+1) + 5(x-1) = 3x
6x + 6 + 5x -5 = 3x
8x = -1
x = -1/8
i think it’s right
6(x+1) +5(x-1) = 3x and you should be able to solve from there. Good luck
the least common denominator is x^2 – 1
multiply 6 / x-1 by (x+1)/x+1) and you get 6(x+1)/x^2 – 1
multiply 5/ x+1 by (x-1)/(x-1) and you get 5(x-1)/x^2 – 1
then add the fractions together:
6(x+1)/x^2 – 1 and 5(x-1)/x^2 – 1 equals to [5(x-1)+6(x+1)]/x^2 – 1
[5(x-1)+6(x+1)]/x^2 – 1 subtract 3x / x^2 – 1 so: [5(x-1)+6(x+1)-3x]/x^2 – 1 = 0
expand:
(5x-5+6x+6-3x)/x^2 – 1
(8x+1)/x^2 – 1
